If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.
A compatibility chart is listed in the bulletin. If your substance is not listed, then we recommend testing this by diluting the standard protein samples in the same buffer as the unknown samples.
The Bradford Reagent requires no dilution and is suitable for micro, multiwell plate, and standard (cuvet) assays. The linear concentration range is 0.1-1.4 mg/mL of protein, using BSA (bovine serum albumin) as the standard protein.
he protein-dye complex is stable up to 60 minutes. The absorbency of the samples must be recorded before the 60 minute time limit and within 10 minutes of each other.
The micro assay using this same reagent may be an option for you. The micro assay is used when a large volume (at least 1 mL) of a dilute sample is available for testing. The linear concentration range of this assay is lower than the standard or multiwell plate assays, (1-10 μg of total protein in 1 mL).
No, we do not supply the BSA standard with this reagent. We recommend using one of the following products: Protein Standard (BSA) Solution, (2 mg/mL), Product No. P0834 or Protein Standard (BSA) Solution, (1 mg/mL), Product No. P0914, if lower concentrations of protein are to be measured.
